I am using ArcGIS 10.2.2 and ModelBuilder. I have a set of models that work and have been tested.
I notice that if I run through the models one after another the open dialogue becomes very slow to open and sometimes freezes. However if I close and re-open ArcCatalog before running, then the model opens OK. This is consistent behavior on different PCs.
My question is, is there some command, or python script I can add at the end of the model that will cause a "re-set" in the same way as closing ArcCatalog? I found a tool on clear cache, but it only relates to ArcSDE.
This is probably yet another quirk of ModelBuilder, but any shared experience would be useful to know.
